«من كانت الآخرة همه جعل الله غناه في قلبه وجمع له شمله وأتته الدنيا وهي راغمة ومن كانت الدنيا همه جعل الله فقره بين عينيه وفرق عليه شمله ولم يأته من الدنيا إلا ما قدر له»
The Prophet (peace and blessings be upon him) said:
"Whoever makes the Hereafter his concern, Allah Almighty places his self-sufficiency in his heart, gathers his scattered affairs for him, and the world comes to him humbled. And whoever makes this world his concern, Allah Almighty places his poverty before his eyes, scatters his affairs, and he receives nothing of this world except what has been decreed for him."
